import_passwords fails on large file with MySQL database

Hi there!

I'm attempting to import a large (1.3GB) text file full of passwords into 
Pyrit's MySQL database and it has failed repeatedly.

The file in question is very high-quality (UNIQPASS v11, 
https://dazzlepod.com/uniqpass/) so I'm confident that it's not causing the 
issue.  I'm using a MySQL database as my default storage as configured with 
~/.pyrit/config.

My system is a quad-core AMD CPU running 64-bit Ubuntu 12.10.

When I run <pyrit -i UNIQPASS.txt import_passwords> it runs for some variable 
length of time before crashing.  (Same issue is present in a detached screen 
session as in a remote shell.)

Strange thing is, it produces a different error and crashes after a different 
number of lines each time I run it (asterisks are mine for readability):

Considering that Pyrit is supposed to be a robust and scalable tool that can 
manage massive databases, I hope this is just me! Please let me know if there 
is anything I can do to help troubleshoot or if I'm missing something.

Thanks for making a great tool.
